Num 10:1 Yahveh spoke to Moses, and this is what he said,
Num 10:2 “Make two silver trumpets. You will make them of hammered work, and you will use them for convening the congregation and for breaking camp.
Num 10:3 And when both are blown, all the congregation will gather themselves to you at the entrance of the conference tent.
Num 10:4 But if they blow only one, then the leaders, the heads of the tribes of Israel, should gather themselves to you.
Num 10:5 When you blow an alarm, the camps that are on the east side will set out.
Num 10:6 And when you blow an alarm the second time, the camps that are on the south side will set out. An alarm is to be blown whenever they are to set out.
Num 10:7 But when the assembly is to be collected, you will blow a long blast, but you will not sound an alarm.
Num 10:8 And the sons of Aaron, the priests, will blow the trumpets. The trumpets will be to you for a permanent prescription throughout your generations.
Num 10:9 And when you go to war in your land against the adversary who oppresses you, then you will sound an alarm with the trumpets, that you may be remembered in the sight of Yahveh your God, and you will be saved from your enemies.
Num 10:10 On the day of your gladness also, and at your appointed feasts and at the beginnings of your months, you will blow the trumpets over your ascending offerings and over the sacrifices of your offering for healthy relationshipss. They will be a reminder of you in the sight of your God: I am Yahveh your God.”

trademark trumpets

Some sounds are almost universally recognizable: the horns of trains or boats, a siren, a church bell. The two silver trumpets for the Israelite community were like that. They were blown in a variety of circumstances, but every time the Israelites heard them, they were to remember the LORD, and the LORD would remember them. It was like an advertising jingle that would spark recognition and memory.

LORD, your silver trumpets are silent today, but we await the sound of the trumpet that will announce the second coming of your Son. Come, Lord Jesus.
